What is a common name for an electronic detection system that triggers alarms?

An electronic intrusion detection system is commonly recognized for its role in triggering alarms when unauthorized activity is detected. This type of system comprises various sensors and devices designed to monitor specified areas for signs of intrusion, such as motion or the opening of doors and windows. When these sensors detect an abnormal condition, they activate alarms, alerting the occupants or security personnel to potential security threats.

The term “electronic intrusion detection system” encompasses a wide range of technologies and methods, including but not limited to motion detectors, glass break sensors, and door contacts. This system centralizes various detection technologies to provide a comprehensive security solution.

In contrast, while terms like "duress alarm" and "motion detector" describe specific types of alarms or sensors, they do not capture the full spectrum of the capabilities inherent in an electronic intrusion detection system. A duress alarm, for instance, is typically a specific signal sent out discreetly during a threatening situation, while a motion detector only focuses on detecting movement without the broader context of intrusion detection systems. The term “electro-mechanical system” is too broad and not specifically related to the function of triggering alarms in the context of security.
